Tools/Materials Method/Steps
1
The sampler stands on the side of the subject and asks the subject to descend. Only the nostrils and nozzle reflections appear. The subject can be covered with an elbow or a paper towel. The subject is not facing the subject and the reaction risk is relatively low.
2
The sampler gently supported the concealment of the person being collected with one hand, and entered the nostril with the swab in the other, and leaned deeply back along the bottom of the nose of the lower passage. Because the nasal passage was curved and weak, it suddenly became traumatic. When the swab floods into the back wall of the nasopharyngeal cavity, it is portable and rotated once. If it encounters a reflex scan, there should be a moment, and then the swab is aspirated, and the swab head is immersed in a tube containing 2∽3mL virus preservation solution.
3
"One insertion, two stopping and three rotations"-measuring the length of time from the tip of the nose to the front of the ear, usually about 4 cm; a pack of 15-30 cm to absorb possible distance objects from the nasopharynx, depending on the subject The degree is certain, only the time is indeterminate and 3 seconds; rotate the eye catcher for 1 circle and then catch it.
